GB/T 45369-2025 Absorbent sanitary paper products and raw materials - Evaluation method of deodorant performance
1 Scope
This document describes four methods for evaluation of the deodorant performance of absorbent sanitary paper products and raw materials: detector tube method, gas detector method, LC-MS/MS method and GC-MC method.
This document is applicable to the evaluation of deodorant performance for absorbent sanitary paper products, including but not limited to baby diapers (pads, liners), adult diapers (pads, liners), sanitary napkins (pantiliners), women's sanitary pants, pet pads (pants), and paper cat litter. It is also applicable to the evaluation of deodorant performance for raw materials such as superabsorbent polymers, fluff pulp, top sheets, composite absorbent cores, distribution layers, absorbent paper, and airlaid paper. It may also serve as a reference for other cat litters.

GB/T 27417 Confirmation assessment - Guidance on validation and verification of chemical analytical methods
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
unpleasant odor
unpleasant odor associated with the environment in which people live
Note: For example, excrement odor, body odor, etc.
3.2
chemical components of unpleasant odor
main chemical components of unpleasant odor in people's living environment
3.3
deodorant performance
desired purpose of reducing odor in the surrounding air
Note: The expression of deodorant performance includes but is not limited to odor purification, odor removal, etc.
3.4
evaluation of deodorant performance
measured reduction rate of the chemical components of unpleasant odor in the specimen-containing container compared with the blank test without specimen
4 Principle
Place the test specimen and a specified initial concentration of chemical components of unpleasant odor into a sampling bag or conical flask. After allowing the specimen to interact with the chemical components of unpleasant odor for a predetermined duration, measure the concentration of these components in both the specimen-containing and specimen-free sampling bags or conical flasks using detector tube method, gas detector method, LC-MS/MS method and GC-MC method. Calculate the reduction rate of each chemical component of unpleasant odor to evaluate the deodorant performance.
